|Above, the tips of the hairs on a Salvina molesta leaf stick to water with enough force to keep this droplet from rolling off when the leaf is turned to the vertical. Below, optical micrograph of eggbeater-shaped hairs on the leaf surface of the aquatic plant Salvinia molesta. The hairs reduce friction and help the plant stay afloat. Ohio State University engineers have replicated the surface in a plastic coating that could reduce drag and boost buoyancy on boats and submarines. Images courtesy of Ohio State University.|
